Make SwitchInstProfUpdateWrapper strict permanently
We have been using -switch-inst-prof-update-wrapper-strict set to true
by default for some time. It is time to remove the safety stuff and make
SwitchInstProfUpdateWrapper intolerant to inconsistencies in !prof
branch_weights metadata of SwitchInst.
This patch gets rid of the Invalid state of SwitchInstProfUpdateWrapper
and the option
-switch-inst-prof-update-wrapper-strict. So there is only two states:
changed and unchanged.

[WebAssembly] Add -fwasm-exceptions for wasm EH
Summary: This adds `-fwasm-exceptions` (in similar fashion with
`-fdwarf-exceptions` or `-fsjlj-exceptions`) that turns on everything
with wasm exception handling from the frontend to the backend.
We currently have `-mexception-handling` in clang frontend, but this is
only about the architecture capability and does not turn on other
necessary options such as the exception model in the backend. (This can
be turned on with `llc -exception-model=wasm`, but llc is not invoked
separately as a command line tool, so this option has to be transferred
from clang.)
Turning on `-fwasm-exceptions` in clang also turns on
`-mexception-handling` if not specified, and will error out if
`-mno-exception-handling` is specified.
